NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 238,506, dated March 8,1881. Application filed May 20, 1880. (No model.)

To all whom tt may concern Be it known that we, JOSIAH R. JONES, FRED-ERIoK HOISINGTON, and ANDERSON L. WIL- LIAMS, citizens of the UnitedStates, residing at North Lewisburg, in the county of Champaign andState of Ohio, have invented certain new and useful Improvements in Nut-Locks, of which the following is a specification.

This invention relates to that class of nutlooks in which are employed,in combination with the fish-bar, a plateto pass over the nuts of thebolts and a locking device for the purpose of preventing the nuts beingdisplaced.

Our improvement consists in providing the under or washer plate with asuitable number of perforations, through which pass the bolts andlocking-staple, and the upper or-lockingplate formed with perforationsfor the staple, which correspond with the perforations in thewasher-plate, and with a suitable number of rectangular openings, whichfit over the edges of the nuts and prevent them from turning andbecoming loose.

It also consists in securing the plates to 5 each other by means of astaple, the ends of which are bent over the locking-plate, all as Willbe hereinafter more fully described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a perspective view of arailroad-rail embodying our invention. Fig. 2 are detailed perspectiveviews of the plates A B and staple C. Fig. 3 is a verticalcross-section.

A on the annexed drawings is the Washerplate, formed with perforations aa, through which pass the ends of the bolts E. This plate A is alsoprovided with smaller perforations 1) 1) near its center, to receive astaple, O.

The locking-plate B is provided with rectangular openings B, one of thesides of which I prefer to leave open, as shown. These openings are of acorresponding size to the nuts to be secured. The plate B is alsoprovided with perforations or staple-holes b b, which correspond inposition with similar perforations, 1) b, in the washer-plate A.

When the bolts E have been inserted in the fish-plate and rail, theplate A, in which the stapleO has been previously inserted, is placedupon the bolts E, and the nuts D screwed home, the plate A thus forminga washer, which holds the staple O firmly in place. The nuts E of thebolts are locked by adjusting the plate B over the washer-plate A, theends of the staple O passing through the perforations 1) b, and thenotches B over the nuts E. The ends of the staple are then benthorizontally or vertically upon the plate B by any suitable instrument,thus holding the plate B securely in place and effectually locking thenuts.

Though having shown our invention applied to a railroad-rail joint, itis evident that it can be eflicaciously and cheaply applied to otherdevices where it is desirable to secure nuts against displacement.

No broad claim is made in this application for a staple, per so, as afastening device, nor do we claim the combination of a fish-bar, alocking-plate, and a staple as our invention.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

Jointly with the rails, fish-plates, or other plates adjacent andattached thereto, and the bolts and nuts, a nut-locking bar providedwith notches or mortises for inclosing or embracing the edges of two ormore nuts. and a bent rod or staple of which the how portion passesbehind, and whose limbs pass outward 8o therefrom and through thefish-plate or other adjacent plate, and also through the nut-lockingbar, which latter it holds firmly in place by having the ends of itslimbs bent over against the surface of the said bar, as set forth.

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
